debugging into unit tests with the new mvn build setup
Hi,
How do you attach the debugger in eclipse to debug into a single unit test now, with the new mvn build setup? If somebody could add instructions for this into the Hive Developer FAQ<https://cwiki.apache.org/confluence/display/Hive/HiveDeveloperFAQ>, that would be great.
Thanks,
Eric

Thanks Brock! I updated the wiki to put in instructions on how to do this.

Perfect, that is a true unit test. With the class open and the method you want to test highlighted you should be able to go to run -> debug. I set a breakpoint the class and verified this work for me. See this, here is an image of it working just a few seconds ago: http://i.imgur.com/eYi6ud6.png

Hi Brock,
I wanted to attach the debugger in eclipse to execution of a junit test in org.apache.hadoop.hive.ql.exec.vector.TestVectorizationContext.

Hi,
Specifically which test are you referring to?
A true unit test is debuggable via the debug menu without any additional work (e.g. the new UDF tests or TestMacroSemanticAnalyzer). The so called "unit" tests that submit MR jobs might be a little more work, but are you looking to debug the parent process or the child process?
